Devarda’s alloy is primarily used as a reducing agent in analytical chemistry, particularly for the quantitative determination of nitrates and nitrites. It is employed in the reduction of nitrate ions to ammonia in alkaline solutions, which can then be distilled and measured. This process is crucial in environmental testing, water quality analysis, and soil science to assess nitrate contamination. Additionally, it finds application in organic synthesis for the reduction of nitro compounds to amines, aiding in the production of various pharmaceuticals and industrial chemicals. Its strong reducing properties make it a valuable tool in laboratories for precise chemical analysis and synthesis.
